| Abstract: |
| 【Objective】To explore the effect of the amount and frequency of the feed on the growth, development and fruit quality of tomato under the nutrient solution model of alternate drip irrigation in the root-splitting zone. 【Methods】The experiment was conducted in a completely random block design, with the liquid supply volume: 450ml(T1), 650ml (T2), 850ml (T3), and the liquid supply frequency: 3 days/time (C1), 2 days/time (C2), and 1 day/time (C3) for 9 treatments.【Results】The increase of nutrient liquid supply would reduce the quality of tomato fruit, which was not conducive to the accumulation of soluble solids. In terms of fruit quality, the content of soluble solids in T1C2 treatment was 6.97%, the weight of single fruit is suitable, the incidence of umbilical rot was low, and the fruit Vitamin C content was the highest. Secondly, T1C2 has the highest water use efficiency (67.06/kg.m-3), which is 154.40% higher than CK, greatly reduces the waste of agricultural water resources and achieves the goal of optimal tomato yield and water saving. In terms of fruit yield, the total yield of tomato treated with T2C3 was the largest, was 13409.10kg/667m2. Compared with CK, the yield of T2C3 increased by 2886.4 kg and up to 27.4%.The single fruit weight of T2C3 treatment tomato can be up to 226.44g, and the fruit weight is relatively large, the color is ruddy, and it has good commercial property. In addition, the water use efficiency of T2C3 treatment was 40.29/kg.m-3, which was 52.85% higher than that of CK, indicating that T2C3 treatment could improve water use efficiency while increasing yield.【Conclusion】As far as fruit quality is concerned, T1C2 treatment, that is, under the mode of alternate drip irrigation in root area, the amount of liquid supplied by drip irrigation per plant is 450 ml, and the liquid supply frequency is 2days / time, which is the ideal liquid supply quantity and liquid supply frequency. In terms of fruit yield, T2C3 treatment, that is, under the mode of alternate drip irrigation nutrition solution in separate root areas, each plant drip irrigation 650ml nutrient solution per day was the ideal liquid supply volume and liquid supply frequency. |
